DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

0040Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

0041As shown in <figref idref="DRAWINGS">FIG. 1</figref> to <figref idref="DRAWINGS">FIG. 12</figref>, the present invention discloses a water saving control mechanism. The water saving control mechanism comprises a main body 1 and a dynamic distribution device 2 disposed in the main body 1. The main body 1 comprises a three-way casing which has a water inlet 13, a first water outlet 11 communicating with a first shower head P1, and a second water outlet 12 communicating with a second shower head P2. The dynamic distribution device 2 comprises a stopper 21 disposed in the water channel of the main body 1 and a drive assembly 22 which is driven by the water flow to bring the stopper 21 to move. The stopper 21 is disposed between the first water outlet 11 and the second water outlet 12. When the stopper 21 is driven by the drive assembly 22, the stopper 21 is adapted to block the first water outlet 11 and the second water outlet 12 alternatively, such that the first shower head P1 and the second shower head P2 are to discharge water by turns.

0042As shown in <figref idref="DRAWINGS">FIG. 3A</figref> and <figref idref="DRAWINGS">FIG. 3B</figref>, the main body 1 is a cylindrical casing. In this embodiment, the water inlet 13 is disposed at a radial position of the main body 1. The first water outlet 11 and the second water outlet 12 are disposed at the same radial circumference as the water inlet 13. The main body 1 has a guide water channel 14 therein for guiding the water from the water inlet 13 to the axial end of the main body 1 and then to enter a main water passage 15. An outer end of the main body 1 is provided with a socket 16 for retaining the shower head, such as the first shower head P1 which can be a movable shower head.

0043The water inlet 13 may be directly disposed at the axial end of the main body 1. In this manner, there is no need for the guide water channel as shown in <figref idref="DRAWINGS">FIG. 11</figref> and <figref idref="DRAWINGS">FIG. 12</figref>.

0044As shown in <figref idref="DRAWINGS">FIG. 4A</figref> to <figref idref="DRAWINGS">FIG. 4C</figref>, the drive assembly 22 comprises an impeller 221 disposed at a front end of the main water passage 15. A rear portion of the impeller 221 is connected with the stopper 21. The drive assembly 22 further comprises a decelerator 222 disposed between the impeller 221 and the stopper 21. The decelerator 222 can be composed of a gear set 223. It also can be composed of a gear set 223, a transmission member 224, and a toothed ring 225.

0045An upper portion of the stopper 21 is formed with a mating seat 212 for accommodating the gear set 223, and a lower portion of the stopper 21 is a post having an axial trough 211 at one side thereof.

0046The transmission member 224 coupled with the gear set 223 and the stopper 21 coupled with the gear set 223 are mounted in the toothed ring 225. The impeller 221 is connected with the transmission member 224 to constitute the dynamic distribution device 2.

0047The dynamic distribution device 2 is sealed in the main water passage 15 of the main body 1 by a press cover 3. The press cover 3 is formed with an inclined water inlet 31 for forming the water flow to drive the impeller 221.

0048As shown in <figref idref="DRAWINGS">FIG. 5</figref>, for a diversity of the water saving control mechanism, the main body 1 is further provided with a static distribution device 4. The static distribution device 4 comprises a switch member 41, a distribution member 42, and a switch handle 43. The switch member 41 is disposed on the stopper 21 and sleeved by the distribution member 42 to cooperate with the distribution member 42 in an airtight manner. The distribution member 42 is disposed at the first water outlet 11 and the second water outlet 12 of the main body 1. The distribution member 42 includes a first distribution outlet 421 and a second distribution outlet 422 to communicate with the first water outlet 11 and the second water outlet 12, respectively. The switch member 41 is connected with the switch handle 43 disposed outside the main body 1 to be turned synchronously for selectively controlling the distribution outlets of the distribution member 42 to discharge water. A stop pin 44 is provided between the switch handle 43 and the main body 1 for the user to know the switch position.

0049As shown in <figref idref="DRAWINGS">FIG. 6A</figref> to <figref idref="DRAWINGS">FIG. 6C</figref>, when in use, the water flow drives the impeller 221 to turn. The impeller 221 is decelerated by the decelerator 222 to bring the stopper 21 to move circumferentially. The switch handle 43 brings the switch member 41 synchronously. When a first water cavity 414 and a second water cavity 415 of the switch member 41 correspond in position to the first distribution outlet 421 and the second distribution outlet 422 of the distribution member 42 and the trough 211 of the stopper 21 is aligned with the first water cavity 414, the first shower head P1 communicating with the first water outlet 12 of the main body 1 is to discharge water, meanwhile, the other side of the stopper 21, opposite to the groove 211, is to block the second water cavity 415, such that the second shower head P2 communicating with the second water outlet 12 of the main body 1 is closed. When the trough 211 of the stopper 21 is aligned with the second water cavity 415, the second shower head P2 communicating with the second water outlet 12 of the main body 1 is to discharge water, meanwhile, the other side of the stopper 21, opposite to the groove 211, is to block the first water cavity 414, such that the first shower head P1 communicating with the first water outlet 11 of the main body 1 is closed. In this way, the first shower head P1 and the second shower head P2 are to discharge water by turns. This way can relieve fatigue and save water.

0050As shown in <figref idref="DRAWINGS">FIG. 7A</figref> to <figref idref="DRAWINGS">FIG. 7F</figref>, the front of the switch member 41 is formed with a switch seat 411 to mate with the distribution member 42. The rear of the switch member 41 is formed with an end head 412 to mate with the switch handle 43. The middle of the switch member 41 is formed with a receiving cavity 413 to receive the stopper 21. The side wall of the switch member 41 is formed with a first water cavity 414 and a second water cavity 415 corresponding to the first water outlet 11 and the second water outlet 12 of the main body 1. In this embodiment, the first water cavity 414 and the second water cavity 415 are disposed oppositely. The outer wall of one side of the switch seat 411 between the first water cavity 414 and the second water cavity 415 is provided with a recess 416 to accommodate a sealing gasket 46. The outer wall of another side of the switch seat 411, opposite to the recess 416, is formed with a reduced cavity 417. The front end surface of the switch seat 411 is provided with an outlet 410 communicating with the reduced cavity 417. An elastic sealing member 45 is provided in the first water cavity 414 and the second water cavity 415 of the switch member 41 to mate with the distribution member 42 in an airtight manner. The elastic sealing member 45 comprises a spring 451, a frame 452, and a sealing ring 453. This arrangement ensures the airtightness when the switch member 41 is turned relative to the distribution member 42.

0051As shown in <figref idref="DRAWINGS">FIG. 8A</figref> and <figref idref="DRAWINGS">FIG. 8B</figref>, the distribution member 42 is a cylindrical sleeve. The side wall of the distribution member 42 is provided with a first distribution outlet 421 and a second distribution outlet 422 corresponding to first water outlet 11 and the second water outlet 12 of the main body 1. The outer wall of the distribution member 42 is provided with a protruding wall 423 in cooperation with the sealing member to mate with the inner wall of the main body 1 in an airtight manner to form the first outlet cavity and the second outlet cavity, preventing the first water outlet 11 and the second water outlet 12 from connecting with each other.

0052Referring to <figref idref="DRAWINGS">FIG. 9</figref> and <figref idref="DRAWINGS">FIG. 10</figref>, the working principle of the present invention is described hereinafter. The switch handle 43 is rotated to bring the switch member 41 until the first water cavity 414 and the second water cavity 415 of the switch member 41 face the first distribution outlet 421 and the second distribution outlet 422 of the distribution member 42 respectively, or the second distribution outlet 422 and the first distribution outlet 421 of the distribution member 42 respectively. At this time, the water channels of the first shower head P1 and the second shower head P2 are in an open state to discharge water by turns because the stopper 21 is turning.

0053The switch handle 43 is rotated to bring the switch member 41 to rotate until the reduced cavity 417 of the switch member 41 is aligned with the first distribution outlet 421 of the distribution member 42. At this time, the first water cavity 414 and the second water cavity 415 of the switch member 41 are not in communication with the first distribution outlet 421 and the second distribution outlet 422 of the distribution member 42. The water flows from the outlet 410 at the end surface of the switch member 41 to enter the reduced cavity 417 to flow out through the first distribution outlet 421, such that the water flows out through the first shower head P1 only. Meanwhile, the sealing gasket 46 on the recess 416 of the switch member 41 is aligned with the second distribution outlet 422 of the distribution member 42 to block the second distribution outlet 422, so the water won't flow out through the second shower head P2.

0054The switch handle 43 is rotated to bring the switch member 41 to rotate until the reduced cavity 417 of the switch member 41 is aligned with the second distribution outlet 422 of the distribution member 42. At this time, the first water cavity 414 and the second water cavity 415 of the switch member 41 are not in communication with the first distribution outlet 421 and the second distribution outlet 422 of the distribution member 42. The water flows from the outlet 410 at the end surface of the switch member 41 to enter the reduced cavity 417 to flow out through the second distribution outlet 422, such that the water flows out through the second shower head P2 only. Meanwhile, the sealing gasket 46 on the recess 416 of the switch member 41 is aligned with the first distribution outlet 421 of the distribution member 42 to block the first distribution outlet 421, so the water won't flow out through the first shower head P1.

0055When the switch handle 43 is rotated to bring the switch member 41 to rotate until the reduced cavity 417 and the first water cavity 414 or the reduced cavity 417 and the second water cavity 415 are located at the two sides of the first distribution outlet 421, the water flows out from both the first shower head P1 and the second shower head P2. Similarly, when the switch handle 43 is rotated to bring the switch member 41 to rotate until the reduced cavity 417 and the first water cavity 414 or the reduced cavity 417 and the second water cavity 415 are located at the two sides of the second distribution outlet 422, the water flows out from both the first shower head P1 and the second shower head P2.

0056Accordingly, the present invention uses the main body 1 which is a three-way configuration and the dynamic distribution device 2 disposed in the main body 1 for water outflow by turns through different outlets. When the present invention is used to take a shower, it not only saves water but also provides a massage effect to relieve fatigue. In addition, the main body 1 is further provided with the static distribution device 4 having the switch member 41 to achieve water outflow in different ways.

0057Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
